Airline pilots have called for some handheld laser pointers to be banned after a number of pilots were dazzled while landing at Dublin airport.
IALPA’s Captain Adrian Hinkson of said the planes were hit with the laser lights at a critical time and pilots could be left temporarily blind by the beams.
Captain Hinkson said the lasers should be classified as weapons making it illegal to possess one except under license.
The Irish Aviation Authority has said ten such incidents have taken place since September and that gardaí have used aerial support to try and pinpoint the laser sources.
Aer Lingus has said six of their flights have been targeted with laser light beams in recent months.
A spokesperson said the pilots advised air traffic control of the incidents immediately, who then informed gardaí.- rte
I have mine for therapeutic uses: Shine your laser pointer on one of those shallow white mouth ulcers for 1 minute and the next day, it will be much healed, if not all healed with a thicker but normal looking skin in its place.
Worked for me in the past when I didn’t have a bacterial throat infection anyway. But I lost my laser pointer. Just got another one today (650 nm +/1 10, <5m W), so I’m trying it again.
WARNINGS: Be careful! Don’t shine a laser pointer at your eye even for an instant. You can cause permanent eye damage. I wouldn’t even risk shining one on a closed eyelid. Watch out for mirrors too. You can hit your eye by accident in a room with mirrors!
Photobiomodulation, also known as low level laser therapy (LLLT), cold laser therapy, and laser biostimulation, is an emerging medical and veterinary technique in which exposure to low-level laser light or light emitting diodes might stimulate or inhibit cellular function possibly leading to beneficial clinical effects. The technique is also known by the more ambiguous terms phototherapy and laser therapy, which may also be used to describe other medical techniques. Rationales for suggesting particular combinations of wavelength, intensity, duration and treatment interval is somewhat arbitrary and sometimes controversial for different diseases, injuries and dysfunctions; these methods are still being explored and increasingly published by the academic community.
… Certain wavelengths of light at certain intensities (delivered by laser, LED or another monochromatic source) will aid tissue regeneration, resolve inflammation, relieve pain and boost the immune system. The exact mechanism is still being explored and debated but it is agreed that the mechanism is photochemical rather than heat-related.
Observed biological and physiological effects include changes in cell membrane permeability, up-regulation and down-regulation of adenosine triphosphate and nitric oxide. The factors of wavelength, effective dose, dose-rate effects, beam penetration, the role of coherence and pulses (peak power and repetition rates) are still poorly understood…- wiki
